| I have Black ants in my home office. I do not have any plants in the office. How can I control them? Desperate |
| When ants invade your home it's for one reason only: food! They have a sweet tooth and are partial to syrups, jams, preserves and sugar. Ants can be seen making a trail between their nest entrance and the food source as they transport food into the colony to nourish the workers and the queen inside. Where ants become an indoor pest, the only real method of control is to locate the nest or colony by following the trail of ants. The nest can then be treated with an insecticidal dust or spray which is carried into the colony. You can purchase these from any good hardware store. Likely entrance points include holes in walls, possibly around drainage and waste pipes; air bricks; and beneath poorly finished work surfaces and kitchen units, baths and was basins. These should be properly sealed with mortar. If the nest cannot be located because it is beneath a concrete floor, for example, it may be impossible to completely destroy the colony and thus achieve effective eradication. In these situations, treating foraging ants will be largely ineffective although some insecticides are available which provide a residual barrier against them. These insecticides can be applied at points where ants are seen emerging into the building. |
